Description
【発明の詳細な説明】 本発明は鉤棒等の断面寸法測定方法に係り。[Detailed description of the invention] The present invention relates to a method for measuring cross-sectional dimensions of hook rods, etc.

何れも一長一、短づよあって、改善が求めら１ている。BACKGROUND ART Conventionally, in the rolling of medium bars of wire rods, round steel, billets, etc., shape measurement ε and devices for each glaze have been used to determine the cross-sectional dimensions and profile of the product. As methods and devices for this, fixed type, single rotation type, swinging type, etc. are known.
Each has its strengths and weaknesses, and improvements are needed.

き７）い欠点がある。+ In other words, the fixed dowel corresponds to the top and bottom of the product cross section, and the oval. This is a method of measuring by fixing an optical measuring device to Therefore, although this method has the advantage of being able to continuously measure the top and bottom A and the oval B, it is not possible to measure the midpoint between the top and bottom and the oval even though it is necessary for wear control of the grooved roll 2. 7) There are some disadvantages.

にも拘らず１回転式によると、中間点も天地、オーバル
と同等々頻度で測定さｈることにｋつて好ましくない。On the other hand, the single rotation type or swing type is a measurement method in which the optical measuring device is relatively rotated in the circumferential direction of the product. For this reason, the cross-sectional profile of the product is scanned in a spiral across the rolling direction.
Both oval and intermediate points can be measured continuously at the same frequency.6However, for example, the intermediate point is sometimes used as a reference to evaluate the roundness of one surface of a rolled bar, etc. However, according to the one-turn method, it is not preferable that the midpoint is measured as frequently as the top, bottom, and oval, even though it is determined by the top, bottom, and oval.
本発明は上記欠点の解決を目的とし、具体的には、全周
にわたって製品プロフィルが連続的に測定できると共に

。That is, in the method of the present invention, two optical receiving systems, each consisting of a collimated light source and a detector thereof, are placed around the chest circumference of a billet, hook bar, etc. with a phase shift of approximately 90°, and are continuously arranged at the start of rolling. The billet is rotated to measure the cross-sectional profile of the billet, copper rod, etc., and then the optical measurement system is stopped and the billet is rotated.
